Abandoned Well Remediation Research and Development Act

Introduced February 15, 2023

AI-Generated Summary

Updated January 20, 2026 at 3:40 AM UTC

The bill amends the Infrastructure Investment and Jobs Act to require the Secretary of Energy to create a research, development, and demonstration program focused on abandoned oil and gas wells. It aims to improve locating abandoned wells, enhance plugging and remediation methods, reduce methane emissions, protect groundwater, and explore repurposing options such as geothermal energy or carbon storage. The program will involve federal, state, academic, national laboratory, and private‑sector partners and is funded with authorized appropriations through fiscal year 2027.

Key Provisions

  • Defines an “abandoned well” as a non‑used, un‑plugged oil or gas well with no planned future use.
  • Mandates the Secretary of Energy to establish the program within 120 days of enactment, coordinating with relevant federal and state agencies.
  • Directs research to improve data collection on well locations and to develop technologies like LiDAR, optical gas imaging, and magnetic surveys for identification.
  • Calls for studies on how well characteristics affect methane emissions and on cost‑effective, low‑carbon plugging materials and methods.
  • Supports demonstration of repurposing abandoned wells for geothermal power, carbon capture, utilization, and storage.
  • Requires assessment of abandoned wells’ impacts on groundwater quality.
  • Ensures coordination with universities, national laboratories, and the private sector.
  • Authorizes annual funding: $30 M in FY2023, $31.25 M in FY2024, $32.5 M in FY2025, $33.75 M in FY2026, and $35 M in FY2027.

IN THE SENATE OF THE UNITED STATES

February 15, 2023

Mr. Luján (for himself, Mr. Cramer, Mr. Heinrich, and Mr. Mullin) introduced the following bill; which was read twice and referred to the Committee on Energy and Natural Resources

A BILL

To amend the Infrastructure Investment and Jobs Act to require the Secretary of Energy to establish an abandoned wells research, development, and demonstration program, and for other purposes.

1.

Short title

This Act may be cited as the Abandoned Well Remediation Research and Development Act.

2.

Abandoned well remediation research and development

(a)

In general

Title VI of division D of the Infrastructure Investment and Jobs Act (Public Law 117–58; 135 Stat. 1080) is amended by adding at the end the following:

40602.

Abandoned wells research, development, and demonstration program

(a)

Definition of abandoned well

In this section, the term abandoned well means a well originally drilled in connection with oil and gas operations that—

(1)

is not being used;

(2)

has not been plugged; and

(3)

has no anticipated use in oil and gas operations.

(b)

Establishment

Not later than 120 days after the date of enactment of the Abandoned Well Remediation Research and Development Act, the Secretary, in coordination with relevant Federal and State agencies and entities, shall establish a research, development, and demonstration program to improve—

(1)

data collection on the location of abandoned wells;

(2)

the plugging, remediation, reclamation, and repurposing of abandoned wells; and

(3)

strategies to mitigate potential environmental impacts of documented and undocumented abandoned wells.

(c)

Activities

Research, development, and demonstration activities carried out under the program established under subsection (b) shall include activities to improve—

(1)

remote sensor capabilities, light detection and ranging (referred to in this section as LiDAR) capabilities, optical gas imaging, magnetic survey technology, and any other technologies relevant to the efficient identification of abandoned wells;

(2)

understanding of how certain parameters of abandoned wells affect methane emission rates of the wells, including parameters such as well age, well depth, geology, construction, case material, and geographic region;

(3)

the efficiency and cost-efficacy of processes for plugging, remediating, reclaiming, and repurposing abandoned wells, including—

(A)

improvement of processes and technologies for the unique challenges associated with plugging remote abandoned wells;

(B)

use of low carbon, lightweight cement or use of alternative materials and additives for plugging purposes; and

(C)

repurposing of abandoned wells for alternative uses, including geothermal power production or carbon capture, utilization, and storage; and

(4)

understanding of the impacts of abandoned wells on groundwater quality and contamination.

(d)

Coordination

In carrying out the program established under subsection (b), the Secretary shall ensure coordination of activities carried out under the program with—

(1)

institutions of higher education;

(2)

the National Laboratories; and

(3)

the private sector.

(e)

Authorization of appropriations

There are authorized to be appropriated to carry out this section—

(1)

$30,000,000 for fiscal year 2023;

(2)

$31,250,000 for fiscal year 2024;

(3)

$32,500,000 for fiscal year 2025;

(4)

$33,750,000 for fiscal year 2026; and
